Manage the interpretation of geotechnical investigation reports for the
purpose of design of land reclamation, ground improvement and geotechnical
and execution of investigation plans for the selection of most technically
suitable and economically feasible dredging material and sites for use in land
review of contractor and consultant
submitted tenders and technical proposals, designs, and specifications related
to geotechnical engineering works.
technical supervision and quality control of geotechnical investigations, land
reclamation, ground improvement, foundation and earth structures works.
of technical feasibility of ground improvement and foundation works contracts.
Provide technical assistance to sites to assure proper quality control
procedures of land reclamation, ground improvement and foundations works.
supervision of geotechnical aspects of dredging, land reclamation, shoring
protection, ground improvement and
design and feasibility analysis of ground improvement works and foundation
train others in the geotechnical assessment of technical proposals, the
review of geotechnical designs, and
preparation of geotechnical reports.
11.Assessment of geotechnical engineering
practices and evaluation of experiences on land reclamation, ground improvement
and foundation works at different Nakheel Projects and establishment of
compiled lessons learned in this regard for use in future Nakheel Projects to
achieve most technically feasible, cost and time effective construction.
technical opinion on geotechnical
aspects of claims and legal matters when they arise for Nakheel projects (e.g. land reclamation
works, ground improvement and foundations works, etc.)
monitoring of ground improvement projects, including the analysis of
geotechnical data collected during the progress of site works, and after
completion of the works.
14. Assist the
Client General Managers and Project
Managers in promoting and developing the geotechnical knowledge within the Client,
which shall include meeting with potential Developers, Purchasers, Contractors,
and Consulting Engineers, and making technical presentations.
SERVICES TO PREVIOUS CLIENTS :( e.g, NAKHEEL, EMAAR, ALDAR and Other Past Clients):
Expert advise/consultancy, analysis, design
and supervision of geotechnical aspects of dredging, land reclamation, shoring
protection, earth fill, foundation, and offshore works.
of terms of reference for geotechnical investigation studies (field and lab
testing) required for ensuring safe and economic design and durable
construction of land reclamation works, buildings and infrastructure
development on rock and soil.
iii) Evaluate and
interpret results of geotechnical site and lab investigations, and make
recommendations on: i) suitability of
project site and most appropriate type of foundation considering structure,
ground conditions and cost and time constraints, ii) requirement of ground
improvement, and stabilization measures to ensure achieving targeted level of safety, and iii) rock/soil material
engineering design parameters for geotechnical works.
quality control procedures (sampling technique, field and lab testing, verification procedure, etc) to ensure
delivery of geotechnical material (e.g.
rock armour quarry run, filter material, dredged and land fill material, etc)
in full compliance with targeted specifications and standards.
v) Establish design
criteria and conduct analysis and design of geotechnical works dealing with
soil and rock material (e.g. shallow and deep (piling) foundations, ground
improvement works, diaphragm walls, embankments, shoring protection works,
earth and retaining structures, underground excavation support works, tunnels,
ground water control system, etc).
earthquake design parameters and response spectrum for design of buildings and
infrastructure considering regional tectonics and local geology and soil/rock conditions.
vii) Develop a
workable investigation plan for selecting best dredging material and dredging
sites for use in land reclamation for upcoming Client projects to ensure full
compliance with targeted specifications and avoid problems of liquefaction, excessive
fines content, weak materials, piping erosion, creep settlement, and other
durability related problems. Evaluation of properties of dredged material based
on such studies and make recommendations.
best practices for land reclamation works and most effective methods of ground
improvement works for each type of dredging material ensuring compliance with
safety and design requirements (settlement, bearing capacity and resistance to
liquefaction), cost requirements and optimum time of execution.
specifications, codes of practice and quality control methodologies for land
reclamation geotechnical works.
x) Review, make
recommendations and certification of method statements for geotechnical
engineering works submitted by the contractors (e.g. ground improvement, piling, shoring, etc).
geotechnical practices and materials that meets the requirements of safety,
cost effectiveness and timely execution.
in technical meetings representing Client.
xiii) Third party
review of geotechnical studies, design, specifications and make recommendations.
xiv) Provide all
needed geotechnical advise to Client.
